However, the function and mechanism of most C2H2 zinc finger proteins in breast caner (BC) remains unclear. Here, we reported the expression prognosis of C2H2 type zinc finger protein ZNF775 in BC patients and its possible biological mechanism. First, multiple public databases showed that ZNF775 was significantly overexpressed in BC tissues. Interestingly, high expression of ZNF775 was significantly associated with a better prognosis. Immunohistochemistry were used for verification, and the expression of ZNF775 was consistent with the databases. Considering the large heterogeneity of different breast cancer cells, we temporarily selected MCF-7 cell line for verification. In vitro overexpression experiments showed that overexpression of ZNF775 significantly inhibited the proliferation and migration of MCF-7 BC cell. We further combined RNA-sequencing (RNA-seq) and CUT &amp; Tag, and found that overexpression of ZNF775 can down-regulate the expression of most genes in the Wnt signaling pathway. The cBioportal database showed that ZNF775 was negatively correlated with the expression of Wnt5a, suggesting that its downstream target was likely Wnt5a. Finally, we discovered that Wnt5a could partially reverse the inhibitory effect of ZNF775 on MCF-7 BC cell migration through transwell migration experiments.

Recent research examined the efficacy of innovative formulations in the prevention of colorectal cancer. In this study, we evaluated the efficacy of a niosome formulation loaded with Enciprazine hydrochloride (Nio-USAN). We assessed the anti-colorectal cancer characteristics of Nio-USAN by employing several techniques including CCK-8, invasion test, MTT test, flow cytometry, and cell cycle assessment. Quantitative real-time PCR was utilized to assess the transcription of genes linked to apoptosis. The F1-Nio-USAN and F2-Nio-USAN have average sizes of 200 and 500 nm, respectively. The entrapment effectiveness (EE%) of the F1-Nio-USAN and F2-Nio-USAN was measured to be 85.32 ± 0.27 % and 87.12 ± 0.35 %, respectively. The F1-Nio-USAN group exhibited the following percentages of HT-29 cell states: 43 % early apoptosis, 21 % late apoptosis, 7 % necrotic, and 29 % viable. The levels of transcription for cas8, Bid, BAX, cas9, and cas3 were significantly elevated in the treatment groups as compared to the PBS control group (P &lt; 0.001).

Early detection is crucial for improving outcomes, but there is no consensus on the optimal screening approach. Despite advances in diagnosis and therapy, CRC mortality rates remain substantial. Apoptosis and autophagy, key processes in cancer cell death, exhibit complex molecular crosstalk, particularly involving BH-3-only proteins, which present potential therapeutic targets. Recent studies suggest that manipulating these pathways could enhance cancer treatment by exploiting their regulatory networks. The B-cell lymphoma 2 (BCL-2) family proteins, central to apoptosis regulation, are implicated in CRC initiation, progression, and therapy resistance. BH3-only proteins like BIM and PUMA are linked to caspase-independent cell death, suggesting alternative pathways for CRC treatment and highlighting the potential for targeted therapies. This review provides an overview of CRC management, including the current landscape and challenges of screening programs and delves into the interplay between apoptosis and autophagy in CRC cell death. It emphasizes the critical role of BCL-2 family proteins in CRC pathogenesis and calls for future research to focus on developing non-invasive, cost-effective diagnostic biomarkers, establishing prognostic biomarker panels, and defining predictive biomarkers for existing treatments. These advancements are essential for improving screening strategies, therapeutic interventions, and ultimately, patient outcomes and quality of life.</p></div>","PeriodicalId":72083,"journal":{"name":"Advances in cancer biology - metastasis","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667394024000133/pdfft?md5=73acb2fe944f476babf22b8d43839a30&pid=1-s2.0-S2667394024000133-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141847129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
